Description

The field of the invention is that of the design and manufacture of openings such as windows for buildings.

More specifically, the invention relates to a window block for the renovation of a building with thermal insulation from the outside (ITE).

The evolution of environmental standards implies that many buildings must be renovated to avoid heat exchange and in particular the significant consumption of heating or air conditioning.

For this, a widely used solution consists in laying a layer of thermal insulation outside the building.

Indeed, studies tend to show that insulation from the outside provides better performance than insulation from the inside.

In addition, this solution allows the internal volume of the building to be kept equal to the internal volume before renovation. In other words, by insulating from the outside of the building, the insulating layer does not reduce the internal volume of the rooms and the occupants of the building can keep the same useful surface area while benefiting from reduced energy consumption since the heating and / or air conditioning are less important.

In addition to insulation, openings such as doors and windows for example are generally changed. The new openings also reduce the need for heating and / or air conditioning and provide a new "exterior" to the building.

Furthermore, for the sake of comfort, the opening elements, in particular the windows, are provided with a roller shutter (and more generally means for at least partially closing the brightness).

The roller shutter mainly allows to hide the light, that is to say to prevent outside light from entering the building. Another function of these roller shutters is to increase the insulating power of the opening. When the roller shutter is lowered, an air reserve is created between the window and the roller shutter, this air reserve then makes it possible to limit the penetration of fresh or hot air from the outside.

The patent document published under the number EP2333219 describes an assembly for the installation and / or renovation of a window, in a window tunnel of a wall having a layer of thermal insulation from the outside, the assembly comprising:

• a pre-frame intended to be inserted into the window tunnel, the pre-frame having an upper wall and a lower wall opposite one another;
• a chest including means for closing at least partial brightness intended to close one end of the pre-frame.

The trunk is mounted on an outer periphery of the frame, that is to say it forms an outer border of the frame.

The assembly is formed in such a way that it can be inserted through the wall and the insulation from the outside, the opening of the tunnel and the insulation from the outside being continuous.

However, such an assembly is not without drawbacks.

First of all, this set decreases the brightness entering the building or, at the very least does not make it possible to increase it.

Indeed, the trunk has a height greater than the height of the window frame, the frame comprising the frame and the window opening.

Thus, when the assembly is mounted in the tunnel, the trunk obstructs part of the height of the tunnel and therefore reduces the passage left for the penetration of light.

Then, when the at least partial light shutter means have deployed, they are located in the immediate vicinity of the window. Thus, the insulating air space between the window and the at least partial shutter means of brightness is low and the insulating power of the assembly is correspondingly reduced. To resolve this drawback, the window could be moved back towards the interior of the building, but such displacement is not always possible.

Finally, there is a risk of water infiltration between the wall and the assembly.

When the pre-frame has a layer of peripheral insulation, the infiltration of water (for example rainwater running along the wall between the wall and the insulation from the outside) can reach the peripheral insulation of the whole and degrade it.

The assembly can then lose its insulating power forcing the occupants of the building to increase their heating and / or air conditioning consumption.

Patent documents published under numbers DE102009040532 , EP1464787 and US9140051 describe assemblies for installing and / or renovating a window.

The invention particularly aims to overcome the drawbacks of the prior art.

More specifically, the invention aims to provide an assembly for the installation and / or renovation of a window which allows a passage of increased brightness compared to the prior art.

The invention also aims to provide such an assembly which is simple to install.

The invention also aims to provide such an assembly which provides good insulation between the interior and exterior of the building.

• un coffre incluant des moyens d'obturation au moins partielle de luminosité destinés à obturer une extrémité du pré-cadre,

caractérisé en ce que, le pré-cadre comprend une ceinture périphérique dans laquelle la couche d'isolation thermique par l'extérieur est destinée à venir s'intégrer, la ceinture périphérique présentant une portion supérieure formée par une paroi frontale prolongeant la paroi supérieure sensiblement perpendiculairement, le coffre étant destiné à être monté sur la paroi frontale,
et en ce que la ceinture périphérique présente, sur au moins une paroi supérieure, un déflecteur destiné à venir en appui sur le mur pour router l'eau de pluie ruisselant sur le mur vers le coffre,
et en ce que la portion supérieure de la ceinture périphérique comprend une casquette présentant des ouvertures destinées à évacuer l'eau de ruissellement provenant du déflecteur.These objectives, as well as others which will appear subsequently, are achieved thanks to the invention which relates to an assembly for the installation and / or renovation of a window, in a window tunnel of a wall. having a thermal insulation layer from the outside, the assembly comprising:

• a pre-frame intended to be inserted into the window tunnel, the pre-frame having an upper wall and a lower wall opposite one another;
• a box including at least partial light shutter means intended to close one end of the pre-frame,

characterized in that, the pre-frame comprises a peripheral belt in which the thermal insulation layer from the outside is intended to be integrated, the peripheral belt having an upper portion formed by a front wall extending the upper wall substantially perpendicularly, the trunk being intended to be mounted on the front wall,
and in that the peripheral belt has, on at least one upper wall, a deflector intended to come to bear on the wall in order to route the rainwater dripping on the wall towards the trunk,
and in that the upper portion of the peripheral belt comprises a cap having openings intended to evacuate the runoff water coming from the deflector.

Such an assembly makes it possible to ensure good insulation of the interior of the building with respect to the exterior thanks to the integration of the insulation layer from the exterior into the peripheral belt. No air passage corridor is thus left so that outside air cannot enter the building through the window tunnel.

Furthermore, the positioning of the trunk allows the assembly to be assembled quickly and easily in situ, that is to say at the place of renovation, since the assembly can be directly inserted into the window tunnel.

In addition, the positioning of the box ensures good brightness since it does not require reducing the height of the window or closing it, even partially, the passage through the window tunnel.

The occupants of the building can therefore enjoy good light while being able to cut it off by closing the at least partial light shutter means.

Also, the water flowing against the wall is then directed towards the cap to be evacuated outside the building. This prevents destruction of the insulation layer from the outside.

More specifically, the runoff water is directed onto the top of the roller shutter box to be discharged outside the building, for example by dripping onto the roller shutter when the latter is closed.

According to a preferred embodiment, the pre-frame comprises two side walls opposite one another, the side walls joining the upper wall and the lower wall, the trunk comprising two slides intended to guide the shutter means to the less partial in brightness when they open and close, the slides each being secured to a side wall.

Preferably, the slides are positioned at one end of the pre-frame intended to form the outer end of the pre-frame.

The positioning of the slides makes it possible to create an air reserve between the at least partial light-sealing means and the window, this air reserve acting as a thermal insulator. In addition, the air reserve makes it possible to position an object (for example a flower pot or a weather station probe, without the latter forming an obstacle to the closure of the at least partial light shutter means.

Advantageously, the slides are secured to the trunk to form a block, the block being secured to the pre-frame by fixing the slides on the pre-frame.

The fixing of the trunk is thus simplified since only the guides are secured to the pre-frame.

This allows easier maintenance interventions and in particular an easy replacement since only the slides are fixed to the pre-frame.

According to a particular embodiment, the upper wall, the lower wall and the side walls each have a folded outer edge forming a groove intended to receive a covering profile partially covering the thermal insulation layer from the outside.

The finishing of the renovation can be made to measure by inserting a covering profile into the groove of the pre-frame, the covering profile possibly being interchangeable as desired, for example depending on events to decorate the building.

Preferably, the cap extends the front wall substantially parallel to the upper wall.

The cap allows on the one hand the positioning of the trunk and, on the other hand, to facilitate the runoff of rainwater seeping against the mus outwards.

For this, the cap may advantageously be inclined towards the lower wall of the pre-frame.

Advantageously, the pre-frame carries on its periphery an insulating element intended to be interposed between the pre-frame and the window tunnel.

This insulating element improves the airtightness of the window block (pre-frame, roller shutter block and window frame). This is particularly verified when the insulating element extends from the outer limit to the inner limit of the window tunnel.

Similarly, the seal is further improved when the insulating element extends over the entire periphery of the pre-frame.

Other characteristics and advantages of the invention will appear more clearly on reading the following description of a preferred embodiment of the invention, given by way of illustrative and nonlimiting example, and of the appended drawings among which:

• the figure 1 is a detail view in perspective from below of an assembly according to the invention;
• the figure 2 is a schematic detail view in cross section of the assembly according to the invention inserted in a window tunnel of a building.

• un pré-cadre 2 sur lequel est monté un dormant 3 d'un ouvrant, et
• un coffre 4 incluant des moyens d'obturation au moins partielle de luminosité, en l'occurrence un volet roulant (dont seule une lame 4a est illustrée sur la figure 1), destiné à obturer une extrémité du pré-cadre.

As illustrated on figures 1 and 2 , a set 1 according to the invention comprises:

• a pre-frame 2 on which is mounted a frame 3 of an opening, and
• a trunk 4 including means for closing at least partial brightness, in this case a rolling shutter (of which only one blade 4a is illustrated on the figure 1 ), intended to close one end of the pre-frame.

This assembly 1 is in particular intended for the installation and / or renovation of a window, in a window tunnel 5 of a wall 6 having a layer 7 of thermal insulation from the outside.

• une paroi 21 supérieure ;
• une paroi inférieure opposée à la paroi 21 supérieure ;
• deux parois 22 latérales joignant la paroi 21 supérieure et la paroi inférieure.

The pre-frame 2, which is intended to be inserted in the window tunnel 5, has:

• an upper wall 21;
• a lower wall opposite the upper wall 21;
• two side walls 22 joining the upper wall 21 and the lower wall.

• une portion supérieure 24 formée par une paroi 24 frontale prolongeant la paroi supérieure 21 sensiblement perpendiculairement à celle-ci, et
• une casquette 25 prolongeant la paroi 24 frontale sensiblement parallèlement à la paroi 21 supérieure.

As illustrated in the figure 2 , the pre-frame 2 has a peripheral belt 23, located downstream of the upper wall 21 in the interior to exterior direction of the building and in which the thermal insulation from the outside is intended to be integrated. The peripheral belt 23 extends over the entire periphery of the pre-frame 22 and has:

• an upper portion 24 formed by a front wall 24 extending the upper wall 21 substantially perpendicular thereto, and
• a cap 25 extending the front wall 24 substantially parallel to the upper wall 21.

The peripheral belt 23 comprises, on at least one upper wall formed by the front wall 24, a deflector 231 extending the front wall 24 and intended to come to bear on the wall 6 to route the rainwater flowing on the wall 6 towards the roller shutter box 4, without contact with the masonry and without thermal bridge, as explained below.

The water flowing on the wall 6 is thus guided on the cap 25 which has openings 251 intended to evacuate the runoff water to the outside.

With reference to the figure 1 , the roller shutter box 4 is mounted on the front wall 21.

• un caisson 41 formé de trois parois agencées en un U s'ouvrant vers la paroi inférieure ;
• un capot 42 inférieur monté mobile sur le caisson entre une position d'ouverture dans laquelle le capot 42 est écarté du caisson 41 et une position de fermeture dans laquelle le capot 42 ferme le caisson 41 et ménage avec lui une fente 43 permettant le passage du volet roulant,
• des glissières 44 solidaire du caisson et débouchant dans la fente 43 pour guider le volet roulant lors de son ouverture et de sa fermeture.

The roller shutter box 4 includes in particular:

• a box 41 formed by three walls arranged in a U opening towards the lower wall;
• a lower cover 42 movably mounted on the box between an open position in which the cover 42 is spaced from the box 41 and a closed position in which the cover 42 closes the box 41 and provides with it a slot 43 allowing the passage of the roller shutter,
• slides 44 secured to the box and opening into the slot 43 to guide the shutter during its opening and closing.

More specifically, with reference to the figure 2 , the roller shutter box 4 is fixed to the pre-frame 2 by means of the slides 44. For this purpose, the slides 44 each have at least one fixing plate 441 allowing the slides to be joined, and therefore the box 4, to the side walls 23 of the pre-frame 2, for example using rivets 442.

The box 41 and the slides 44 thus form a rolling shutter block which can be mounted or simply removed from the pre-frame 2, for example for maintenance purposes.

As shown in the figure 2 , the slides 44 are positioned at one end of the pre-frame 2 intended to form the outer end of the pre-frame 2, that is to say the end situated outside the building.

The slides 4 make it possible to provide between the frame 3, more generally the opening, and the roller shutter, when it is closed, a free space 8 which defines a reserve of air contributing to the thermal insulation between the interior and outside the building. Furthermore, this free space 8 can be used to store an object, for example a plant, without the latter interfering with the opening or closing of the shutter.

As shown in the figure 2 , the upper wall 21, the lower wall and the side walls 22 each have a folded outer edge 26 forming a groove 27 intended to receive a covering profile 9 partially covering the layer 7 of thermal insulation from the outside.

This allows in particular to obtain a good quality exterior finish.

To offer air, water and heat tightness, the pre-frame 2 carries on its periphery an insulating element 10 intended to be interposed between the pre-frame 2 and the window tunnel 5.

According to an advantageous embodiment, the box 41 is inclined towards the outside of the building. Thus, when the runoff water, guided by the deflector 231, reaches the cap 25, it is evacuated through the openings 251 of the cap until reaching the trunk 4 of the roller shutter. The inclination of the box 41 then allows the water to be evacuated outside, for example by flowing along the roller shutter when it is closed.

Thus, water cannot stagnate on the box 41 of the roller shutter box 4, at the risk of causing mold and bad odors.

The assembly 1 according to the invention thus makes it possible to benefit from a rolling shutter to allow sound, thermal and light insulation of the interior of the building from the outside without reducing the incoming light when the rolling shutter is open.

Indeed, the positioning of the rolling shutter box 4 outside the tunnel 5, in the insulation layer 7 from the outside, makes it possible not to restrict the height of the tunnel 5 allowing the passage of light.

In addition, water infiltration problems are prevented thanks to the deflector 231 and to the openings 251 of the cap 25, just like the passage of air from the outside to the inside by the presence of the element 10 d insulation around the pre-frame and the reception of the insulation layer 7 from the outside in the peripheral belt 23.

Although the text mentions that the trunk incorporates a rolling shutter, the trunk could integrate any other means of at least partial shutter of brightness such as a blind or a solar shading.
